            MORTGAGE LOAN PURCHASE AGREEMENT ("Agreement") dated as of April 1,
2001 between GreenPoint Mortgage Funding, Inc., a New York corporation
("Seller"), and GreenPoint Mortgage Securities Inc., a Delaware corporation
("Purchaser").

            WHEREAS, Seller desires to sell to Purchaser the Mortgage Loans (as
hereinafter defined), and Purchaser desires to purchase such Mortgage Loans in
accordance with the terms and conditions set forth in this Agreement.

            NOW, THEREFORE, the parties, in consideration of good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged, and
intending to be legally bound, hereby agree as follows:

                                   ARTICLE I

                                   Definitions

            All capitalized terms used in this Agreement and not otherwise
defined herein, shall have the meanings assigned thereto in Annex A to the
Indenture dated as of April 1, 2001, between the Issuer and the Indenture

consideration for the Purchase Price the Seller hereby sells, transfers,
assigns, sets over and otherwise conveys to the Purchaser, without recourse, all
of its right, title and interest in, to and under, whether now existing or
hereafter created, (i) each Mortgage Loan, including its Principal Balance (and

Balance is greater than the cash consideration paid by the Purchaser for such

of such cash consideration shall be deemed to be a combination of a credit for a
capital contribution made to the Purchaser by the Seller and an increase in the
principal amount of the Purchaser Notes pursuant to Article X.

re-transferred to the Purchaser pursuant to Section 2.03 of the Sale and
Servicing Agreement, the Seller shall, at the Purchaser's option, either (a)

            Section 3.01. Intent of Parties; Security Interest. Purchaser and
Seller confirm that the transactions contemplated herein are intended as

related Purchased Assets, Seller shall be deemed to have hereby pledged to
Purchaser as security for the performance by Seller of all of its obligations
from time to time arising hereunder and under any and all Purchases effected
pursuant thereto, and shall be deemed to have granted to Purchaser a security
interest in, the related Purchased Assets and all distributions in respect
thereof, and the proceeds of any and all of the foregoing whether now owned or
hereafter acquired, (collectively, the "Collateral"). In furtherance of the
foregoing, (i) this Agreement shall constitute a security agreement, (ii)
Purchaser shall have all of the rights of a secured party with respect to the
Collateral pursuant to applicable law and (iii) Seller shall execute all
documents, including, but not limited to, financing statements under the Uniform
Commercial Code as in effect in any applicable jurisdictions, as the Purchaser
may reasonably require to effectively perfect and evidence Purchaser's first
priority security interest in the Collateral. Seller also covenants not to
pledge, assign or grant any security interest to any other party in any Mortgage
Loan sold to Purchaser.

      Seller has been duly authorized by all necessary corporate action on the

            (xix) No selection procedure reasonably believed by the Seller to be
      adverse to the interests of the Noteholders or the Insurer was utilized in

      originated in connection with the Seller's mortgage loan origination
      program;

            (xxii) As of the Closing Date with respect to the Mortgage Loans and
      the applicable Transfer Date with respect to any Eligible Substitute

                                       9

      Balances with respect to the Mortgage Loans and such funds as are from
      time to time deposited in the Collection Account (excluding any investment
      earnings thereon) and all other property specified in the definition of
      "Trust" as being part of the corpus of the Trust conveyed to the Trust,
      and upon payment for the Additional Balances, will constitute a valid

      of the Seller in and to the Additional Balances, all monies due or to
      become due with respect thereto, and all proceeds of such Additional

      of any escrow funds therefor have been complied with. All costs, fees and
      expenses incurred in making or closing or recording such Closed End
      Mortgage Loans were paid;

            (xxxv) Each Mortgage contains customary and enforceable provisions
      which render the rights and remedies of the holder thereof adequate for
      the realization against the related Mortgaged Property of the benefits of
      the security, including (A) in the case of a Mortgage designated as a deed
      of trust, by trustee's sale and (B) otherwise by judicial foreclosure.

      or event of acceleration; and the Seller has not waived any default,
      breach, violation or event of acceleration;

      the legal, valid and binding obligation of the related Mortgagor and is
      enforceable by the Purchaser or any transferor of the Purchaser against
      the Mortgagor in accordance with its terms, except only as such
      enforcement may be limited by bankruptcy, insolvency, reorganization,
      moratorium or other similar laws affecting the enforcement of creditors'
      rights generally and by law;

      which remains unpaid and which has been assessed but is not yet due and
      payable. There are no defaults in complying with the terms of any senior

                                       11
<PAGE>

      have not been cured by anyone other than the Servicer, except for any
      payment defaults of less than 30 days. Except for payments in the nature
      of escrow payments, including without limitation, taxes and insurance
      payments, the Seller has not advanced funds, or induced, solicited or

            (xlviii) With respect to each Mortgage Loan, the improvements upon

      insurable value of the Mortgaged Property;

            (xlix) No misrepresentation of a material fact or fraud in respect
      of the origination, modification or amendment of any Mortgage Loan has

      involved in the origination of such Mortgage Loan;

            (l) With respect to the Pool I Mortgage Loans, the terms of the

      the interests of the Purchaser and which has been or will be delivered to
      the Indenture Trustee on behalf of the Purchaser;

            (li) As of the Cut-Off Date, except as otherwise indicated in the

      amortizing Mortgage Loans having an original term to maturity from the
      date on which the first monthly payment is due of not more than 30 years.
      Each Mortgage Note with respect to a fixed rate and balloon Mortgage Note
      will provide for a schedule of substantially level and equal Monthly
      Payments which are sufficient to amortize fully the principal balance of
      such Mortgage Loan over a period of time equal to the amortization period
      of such Mortgage Note; provided, however, that certain Mortgage Loans
      constituting approximately 8.11% of the aggregate balance of the Mortgage
      Loans as of Cut-Off Date are balloon loans that provide for final monthly
      payment substantially greater than the preceding monthly payments. All
      such balloon loans provide for monthly payment based upon a 30 year
      amortization schedule with a final balloon payment no later than the 15th

      program(s) and customary industry standards and included an assessment of
      the fair market value of the related mortgaged property at the time of the
      appraisal. The Mortgage File contains an appraisal of the applicable
      Mortgaged Property;

            (lvi) All individual insurance policies contain a standard mortgagee
      clause naming the Seller, its successors and assigns, as mortgagee. All
      premiums thereon have been paid. Each Mortgage obligates the Mortgagor
      thereunder to maintain all such insurance at the Mortgagor's cost and
      expense, and upon the Mortgagor's failure to do so, authorizes the holder
      of the Mortgage to obtain and maintain such insurance at the Mortgagor's
      cost and expense and to seek reimbursement therefor from the Mortgagor;

            (lvii) Any advances made after the date of origination of a Mortgage
      Loan but prior to the Cut-Off Date have been consolidated with the
      outstanding principal amount secured by the related Mortgage, and the

      and single repayment term reflected on the Mortgage Loan Schedule. The
      consolidated principal amount does not exceed the original principal
      amount of the related Mortgage Loan;

            (lviii) No improvement located on or being part of any Mortgaged
      Property is in violation of any applicable zoning law or regulation. All
      inspections, licenses and certificates required to be made or issued with
      respect to all occupied portions of each Mortgaged Property and, with
      respect to the use and occupancy of the same, including but not limited to
      certificates of occupancy and fire underwriting certificates, have been
      made or obtained from the appropriate authorities and such Mortgaged
      Property is lawfully occupied under the applicable law and all
      improvements which were included for the purpose of determining the
      appraised value of the Mortgaged Property lie wholly within the boundaries
      and building restriction lines of such property, and no improvements on
      adjoining property encroach upon the Mortgage Property;

            (lix) The proceeds of each fixed rate and balloon Mortgage Loan have
      been fully disbursed and there is no obligation on the part of the
      mortgagee to make future advances thereunder and any and all requirements
      as to completion of any on-site or off-site improvements and as to
      disbursement of any escrow funds therefor have been complied with. All
      costs, fees and expenses incurred in making, closing or recording the
      Mortgage Loans were paid and the Mortgagor is not entitled to any refund
      of amounts paid or due under the Mortgage Note;

      in the event the related Mortgaged Property is sold without the prior
      consent of the mortgagee thereunder;

            (lxxiii) To the best of Seller's knowledge, Pool I does not contain
      the first and second lien mortgage loans relating to a single Mortgaged
      Property if the aggregate original principal balance of such mortgage
      loans exceeds Freddie Mac's loan limits. To the best of Seller's
      knowledge, Pool I will not result in a violation of Freddie Mac's loan
      limitations;

            (lxxiv) Each Mortgage Loan was originated substantially in
      accordance with Seller's underwriting criteria, which conform to the
      underwriting criteria set forth in the Prospectus Supplement.

            (lxxv) There exists no violation of any local, state or federal
      environmental law, rule or regulation in respect of any Mortgaged Property
      which violation has or could have a material adverse effect on the market
      value of such Mortgaged Property. Seller has no knowledge of any pending
      action or proceeding directly involving any such Mortgaged Property in
      which compliance with any environmental law, rule or regulation is in
      issue; and, to the best of Seller's knowledge, nothing further remains to
      be done to satisfy in full all requirements of each such law, rule or
      regulation constituting a prerequisite to the use and enjoyment of any
      such Mortgaged Property;

            (lxxvi) The Seller has caused or will cause to be performed any and
      all acts required to be performed to preserve the rights and remedies of
      the Indenture Trustee in any insurance policies applicable to the Mortgage
      Loans including, without limitation, any necessary notifications of
      insurers, assignment of policies or interests therein, and establishments
      of co-insured, joint loss payee and mortgagee rights in favor of the
      Indenture Trustee;

            (lxxvii) The related Mortgage Note is not and has not been secured
      by any collateral, pledged account or other security except the lien of
      the corresponding Mortgage;

            (lxxviii) There is no obligation on the part of the Seller or any
      other party to make payments in addition to those made by the Mortgagor;

            (lxxix) With respect to each Mortgage constituting a deed of trust,
      a trustee, duly qualified under existing law to serve as such, has been
      properly designated and currently so


                                       15
<PAGE>

      serves and is named in such Mortgage, and no fees or expenses are or will
      become payable by the Noteholders or the Trust to the trustee under the
      deed of trust, except in connection with a trustee's sale after default by
      the Mortgagor;

            (lxxx) Each Mortgagor has executed a statement to the effect that
      such Mortgagor has received all disclosure materials including the notice
      of the right of cancellation or rescission required by applicable law with
      respect to the making of the Mortgage Loan and any waiver of any right of
      cancellation or rescission exercised by the Mortgagor was in accordance
      with applicable law and is binding on the Mortgagor.

            (lxxxi) Each of the Mortgaged Properties relating to the seventy-six
      Mortgage Loans included in the sample report provided to the Insurer for
      which a reappraisal is received by the Insurer on or before April 13,
      2001, shall be reappraised for a value that is at least 90% of the
      original appraisal that was provided to the Insurer with respect to such
      Mortgaged Property; the Insurer shall have the discretion to waive such
      requirement.

With respect to the representations and warranties set forth in this Section
4.02 that are made to the best of the Seller's knowledge or as to which the
Seller has no knowledge, if it is discovered by the Purchaser, the Servicer, the
Insurer or a Responsible Officer of the Indenture Trustee that the substance of
such representation and warranty is inaccurate and such inaccuracy materially
and adversely affects the value of the related Mortgage Loan then,
notwithstanding the Seller's lack of knowledge with respect to the substance of
such representation and warranty being inaccurate at the time the representation
or warranty was made, such inaccuracy shall be deemed a breach of the applicable
representation or warranty.

            Section 4.03. Representations and Warranties of Purchaser. Purchaser
hereby makes the following representations and warranties, each of which
representations and warranties (i) is material and being relied upon by Seller
and (ii) is true in all respects as of the date of this Agreement:

            (i) Purchaser has been duly organized and is validly existing as a
      corporation under the laws of the State of Delaware.

            (ii) Purchaser has the requisite power and authority and legal right
      to execute and deliver, engage in the transactions contemplated by, and
      perform and observe the terms and conditions of, this Agreement to be
      performed by it.

            (iii) This Agreement has been duly authorized and executed by
      Purchaser, is valid, binding and enforceable against Purchaser in
      accordance with its terms, and the execution, delivery and performance by
      Purchaser of this Agreement does not conflict with any material term or
      provision of any other agreement to which Purchaser is a party or any term
      or provision of the Certificate of Incorporation or the By-laws of the
      Purchaser, or any law, rule, equation, order, judgment, writ, injunction
      or decree applicable to Purchaser of any court, regulatory body,
      administrative agency or governmental body having jurisdiction over
      Purchaser.


                                       16
<PAGE>

            (iv) No consent, approval, authorization or order of, registration
      or filing with, or notice to any governmental authority or court is
      required under applicable law in connection with the execution and
      delivery by Purchaser of this agreement.

            (v) There is no action, proceeding or investigation pending or, to
      the best knowledge of Purchaser, threatened against Purchaser before any
      court, administrative agency or other tribunal (i) asserting the
      invalidity of this Agreement, (ii) seeking to prevent the consummation of
      any of the transactions contemplated by this Agreement, or (iii) which is
      likely to materially and adversely affect the performance by Purchaser of
      its obligations under, or the validity or enforceability of, this
      Agreement.

            (vi) By the purchase of Mortgage Loans, Purchaser represents to
      Seller that Purchaser understands, and that Purchaser has such knowledge
      and experience in financial and business matters that it is capable of
      evaluating the merits and risks of, its investment in the Mortgage Loans.

            Section 4.04. Remedies for Breach of Representations and Warranties;
Repurchase Obligation. It is understood and agreed that the representations and
warranties set forth in Sections 4.01 and 4.02 shall survive each sale of
Mortgage Loans to the Purchaser and shall inure to the benefit of the Purchaser
and subsequent transferees notwithstanding any restrictive or qualified
endorsement on any Mortgage Note or Assignment of Mortgage or the examination or
failure to examine any Mortgage File. With respect to the representations and
warranties contained in Sections 4.01 and 4.02 which are made to the best of the
Seller's knowledge or to the actual knowledge of the Seller, if it is discovered
by either the Seller or the Purchaser that the substance of such representation
and warranty is inaccurate and such inaccuracy materially and adversely affects
the value of the related Mortgage Loan or the Purchaser's interest therein, then
notwithstanding the Seller's lack of knowledge with respect to the inaccuracy at
the time the representation or warranty was made, the Seller shall repurchase
the related Mortgage Loan in accordance with this Section 4.04 as if the
applicable representation or warranty was breached, subject to the terms and
conditions of the Sale and Servicing Agreement. Upon discovery by either the
Seller or the Purchaser of a breach of any of the foregoing representations and
warranties which materially and adversely affects the value of the Mortgage
Loans or the interest of the Purchaser (or which materially and adversely
affects the interests of the Purchaser in the related Mortgage Loan in the case
of a representation and warranty relating to a particular Mortgage Loan), the
party discovering such breach shall give prompt written notice to the others.

            Within 60 days of the earlier of either discovery by or notice to
the Seller of any breach of a representation or warranty which materially and
adversely affects the value of any Mortgage Loan or the Purchaser's interest
therein, the Seller shall use its best efforts promptly to cure such breach in
all material respects and, if such breach cannot be cured or is not cured or is
not being diligently pursued as evidenced by a notice acceptable to the
Purchaser, as evidenced by the Purchaser's agreement thereto, at the end of such
60-day period, the Seller shall, at the Purchaser's option, either (a)
repurchase such Mortgage Loan at the Repurchase Price or (b) provide an Eligible
Substitute Mortgage Loan, if the Seller has any such loans available for sale at
the time subject to the terms and conditions of the Sale and Servicing
Agreement.


                                       17
<PAGE>

            At the time of repurchase or substitution, the Purchaser and the
Seller shall arrange for the assignment of such Mortgage Loan to the Seller and
the delivery by the Purchaser to the Seller of the related Mortgage Files.

            In addition to such cure and repurchase obligation, the Seller shall
indemnify the Purchaser and hold it harmless against any losses, damages,
penalties, fines, forfeitures, reasonable and necessary legal fees and related
costs, judgments, and other costs and expenses resulting from any claim, demand,
defense or assertion based on or grounded upon, or resulting from, a breach of
the representations and warranties contained in this Article IV (notwithstanding
any limitation in such representation and warranty as to the Seller's
knowledge). It is understood and agreed that the obligations of the Seller set
forth in this Section 4.04 to cure or repurchase a defective Mortgage Loan and
to indemnify the Purchaser as provided in this Section 4.04 constitute the sole
remedies of the Purchaser respecting a breach of the foregoing representations
and warranties.

            Any cause of action against the Seller relating to or arising out of
the breach of any representations and warranties made in Sections 4.01 or 4.02
shall accrue as to any Mortgage Loan upon (i) discovery of such breach by the
Purchaser or notice thereof by the Seller to the Purchaser, (ii) failure by the
Seller to cure such breach or repurchase such Mortgage Loan as specified above,
and (iii) demand upon the Seller by the Purchaser for compliance with the
relevant provisions of this Agreement.

                                   ARTICLE V

                       Covenants and Warranties of Seller

            So long as this Agreement remains in effect or Seller shall have any
obligations hereunder, Seller hereby covenants and agrees with Purchaser as
follows:

            Section 5.01. Affirmative Covenants.

            (a) Until the later to occur of (i) the discharge and payment of all
of Seller's obligations under this Agreement and (ii) the Termination Date of
this Agreement, Seller shall, promptly upon preparation, but in no event later
than 60 days following the end of each such party's first three fiscal quarters,
deliver to Purchaser its unaudited company-prepared financial statements as of
the end of each such fiscal quarter, prepared in accordance with GAAP. Seller
shall, promptly upon preparation, but in no event later than 90 days following
the end of such party's fourth fiscal quarter, deliver to Purchaser its audited
and certified financial statements, prepared in accordance with GAAP, as of the
end of the most recently ended fiscal year, which audits and certifications
shall each be prepared by a nationally recognized independent accounting firm or
by a regionally recognized independent accounting firm with the prior written
consent of Purchaser, which consent shall not be unreasonably withheld. In all
cases, financial statements shall include, without limitation, a balance sheet,
a profit and loss statement and a statement of cash flows. Notwithstanding
anything in this Agreement to the contrary, if (x) the audited and certified
financial statements described in the immediately preceding sentence are not
delivered within the above-specified 90 days, (y) Seller is diligently using its
best efforts to deliver such financial statements, and (z) Seller provides
Purchaser with a notice specifying the


                                       18
<PAGE>

reason for the delay and a date, within a reasonable time period (as determined
by Purchaser), on which such financial statements will be delivered, and they
are so delivered; then failure to deliver such financial statements within the
above-specified 90 days, as the case may be, shall not be deemed to be an Event
of Termination of this Agreement.

            (b) Upon request of Purchaser, Seller shall, to the extent lawful,
promptly upon filing, deliver to Purchaser copies of all material public filings
made by Seller with any governmental or quasi-governmental body.

Seller or any of its affiliates or otherwise use its best efforts to cause to be
delivered to Purchaser monthly, the report, if any, prepared by the relevant
trustee or servicer setting forth payment activity, defaults and delinquencies
with respect to each Mortgage Loan acquired by Purchaser and (ii) prepare and
deliver reports each month, detailing, with respect to all Purchases, such
information as the Purchaser may from time to time reasonably request.

            (d) Seller shall do all things necessary to remain duly
incorporated, validly existing and in good standing as a domestic corporation in
its jurisdiction of incorporation and maintain all requisite authority to
conduct its business in each jurisdiction in which its business is conducted
except where failure to maintain such authority would not have a material
adverse effect on the ability of Seller to conduct its business or to perform
its obligations under this Agreement.

            (e) At all times during this Agreement, Seller shall possess
sufficient net capital and liquid assets (or ability to access the same) to
satisfy its obligations as they become due in the normal course of business.

            (f) Seller will notify Purchaser in writing of any of the following
promptly upon learning of the occurrence thereof, describing the same and, if
applicable, any remedial steps being taken with respect thereto;

            (i) The occurrence or likelihood of occurrence of an Event of
      Termination hereunder;

            (ii) The institution of any litigation, arbitration proceeding or
      governmental proceeding which, in the opinion of counsel to Seller, will
      have a material adverse effect on Seller or the Mortgage Loans;

            (iii) The entry of any judgment or decree against Seller if the
      aggregate amount of all judgments and decrees then outstanding against
      Seller exceeds $10,000,000 after deducting (A) the amount with respect to
      which Seller is insured and with respect to which the insurer has assumed
      responsibility in writing, and (B) the amount for which Seller is
      otherwise indemnified if the terms of such indemnification are reasonably
      satisfactory to Purchaser; or

            (iv) The occurrence or likelihood of any event which would allow the
      obligee under any material loan agreement to which Seller is bound to
      declare an event of default or accelerate the obligations of Seller
      thereunder.


                                       19

            (g) Seller shall permit the Purchaser or its accountants, attorneys
or other agents access to all of the books and records relating to Mortgage
Loans purchased and retained by Purchaser for inspection and copying during
normal business hours at all places where Seller conducts business.

            (h) Seller shall satisfy the obligation under any Credit Line
Agreement that provides for the funding of all future Draws thereunder.

            Section 5.02. Negative Covenants.

any rights hereunder, without first obtaining the specific written consent of
Purchaser.

            (b) Seller shall not amend its Articles of Incorporation or By-laws,
which amendment shall have or is likely to have an adverse effect upon Purchaser
or its interests under this Agreement, without the prior written consent of
Purchaser.

            (c) During the term of this Agreement, Seller shall not engage in
any business other than as a consumer and mortgage finance lender and servicer,
except with the prior written consent of Purchaser.

            (d) Seller shall not (i) dissolve or terminate its existence or (ii)
transfer any assets to any affiliate except as otherwise expressly permitted or
contemplated hereby.

            (e) Except with the written consent of the Purchaser, the Seller
shall not guarantee, endorse or otherwise in any way become or be responsible
for any obligations of any other person, entity or affiliate, including, without
limitation, whether directly or indirectly by agreement to purchase the
indebtedness of any other person or through the purchase of goods, supplies or
services, or maintenance of working capital or other balance sheet covenants or
conditions, or by way of stock purchase, capital contribution, advance or loan
for the purposes of paying or discharging any indebtedness or obligation of such
other person or otherwise; provided, however, that nothing contained herein
shall prevent Seller from indemnifying its officers, directors and agents
pursuant to its By-laws and its Articles of Incorporation.

            (f) Seller will not commit any act in violation of applicable laws,
or regulations promulgated pursuant thereto that relate to the Mortgage Loans or
that materially and adversely affect the operations or financial conditions of
Seller.

            (g) Seller, by entering into this Agreement, hereby covenants and
agrees that it will not at any time institute against the Issuer, or join in any
institution against the Issuer of, any bankruptcy, reorganization, arrangement,
insolvency or liquidation proceedings, or other proceedings under any United

obligations relating to the Notes or any of the Basic Documents.

      affiliates for material misstatements or omissions contained in such

      Purchaser with respect to the preparation of Mortgage Loan documents and

            (viii) to negotiate and execute one or more custodial and servicing
      agreements among the Purchaser, the Seller and a third party

                        Termination; Additional Remedies

            Upon the occurrence of a Rapid Amortization Event due to an act or
omission of the Seller (an "Event of Termination"), the Purchaser and its
assignees shall have, in addition to all other rights and remedies under this
Agreement or otherwise, all other rights and remedies provided under the UCC of
each applicable jurisdiction and other applicable laws, which rights shall be
cumulative. Without limiting the foregoing, the occurrence of an Event of
Termination shall not deny to the Purchaser or its assignees any remedy in
addition to termination of its obligations to make purchases hereunder to which
the Purchaser or its assignee may be otherwise appropriately entitled, whether
by statute or applicable law, at law or in equity.

                                    ARTICLE X

following each day other than the Closing Date on which any Mortgage Loans are
purchased from the Seller by the Purchaser pursuant to Article II hereof or
Additional Balances relating to Mortgage Loans are funded by the Seller, on the
terms and subject to the conditions of this Agreement, the Purchaser shall pay
to the Seller the applicable Purchase Price by (i) making or causing to be made
a cash payment to the Seller or its designee in such amount determined by the
Purchaser, (ii) crediting the Seller with an additional capital contribution to
the Purchaser, (iii) automatically increasing the principal amount outstanding

made on such day to the Seller and/or any capital contribution made by the
Seller to the Purchaser, subject to a cap on such note at any time equal to $30
million or (iv) any combination of the foregoing.

            Section 10.02. The Purchaser Note.

            (a) On the Closing Date, the Purchaser shall deliver to the Seller a
promissory note, substantially in the form of Exhibit A, payable to the order of
the Seller (such promissory note, as the same has been or hereafter may be
amended, supplemented, endorsed or otherwise modified from time to time,
together with any promissory note issued from time to time in substitution
therefor or renewal thereof in accordance with this Agreement, being herein
called the "Purchaser Note"), which Purchaser Note shall, in accordance with its
terms, be subordinated to all interests of the Trust, all claims to the cash
flows from Trust assets and all obligations of the Purchaser, of any nature, now
or hereafter arising under or in connection with the Sale and Servicing
Agreement. The Purchaser Note shall evidence all amounts incurred thereunder
subsequent to the Closing Date as provided in this Agreement. Subject to the

year and one day after the


                                       23

determined by the Indenture Trustee from time to time in effect. The Purchaser
may prepay all or part of the outstanding balance of the Purchaser Note and
interest accrued thereon from time to time without any premium or penalty,

such prepayment or payment.

            (b) The Servicer shall hold the Purchaser Note for the benefit of

            This Agreement, including the Exhibits and Schedules hereto,

                                   Indemnities

            Without limiting any other rights which Purchaser or Seller may have
hereunder or under applicable law, and in addition to any other indemnity
provided hereunder, Seller hereby agrees to indemnify Purchaser and its
respective officers, directors, agents and employees (each, an "Indemnified
Party") from and against any and all Losses incurred by any of them relating to
or resulting from:

            (1) any representation or warranty made by Seller (or any officers,
      employees or agents of Seller) under or in connection with this Agreement,
      any periodic report required to be furnished thereunder or any other
      information or document delivered by Seller pursuant hereto, which shall
      have been false or incorrect in any material respect when made or deemed
      made;


                                       26
<PAGE>

            (2) the failure by Seller to (a) comply with any applicable law,
      rule or regulation with respect to any Purchase or (b) perform or observe
      any material obligation or covenant hereunder; or

            (3) the failure by Seller (if so requested by Purchaser) to execute
      and properly file, or any delay in executing and properly filing,
      financing statements or other similar instruments or documents under the
      Uniform Commercial Code of any applicable jurisdiction or other applicable
      laws with respect to the Mortgage Loans.

            Promptly after receipt by an Indemnified Party under this Article XX
of notice of the commencement of any action, such Indemnified Party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Article XX, notify the indemnifying party in writing of the commencement
thereof; but the omission so to notify the indemnifying party will not relieve
it from any liability that it may have to any Indemnified Party otherwise than
under this Article XX. In case any such action is brought against any
Indemnified Party and it notifies the indemnifying party of the commencement
thereof, the indemnifying party will be entitled to participate therein, and to
the extent that it may elect by written notice delivered to the Indemnified
Party promptly after receiving the aforesaid notice from such Indemnified Party,
to assume the defense thereof, with counsel satisfactory to such Indemnified
Party; provided, however, that if the defendants in any such action include both
the Indemnified Party and the indemnifying party and the Indemnified Party or
parties shall have reasonably concluded that there may be legal defenses
available to it or them and/or other Indemnified Parties that are different from
or additional to those available to the indemnifying party, the Indemnified
Party or parties shall have the right to elect separate counsel to assert such
legal defenses and to otherwise participate in the defense of such action on
behalf of such Indemnified Party or parties. Upon receipt of notice from the
indemnifying party to such Indemnified Party of its election so to assume the
defense of such action and approval by the Indemnified Party of counsel, the
indemnifying party will not be liable for any legal or other expenses
subsequently incurred by such Indemnified Party in connection with the defense
thereof, unless (i) the Indemnified Party shall have employed separate counsel
in connection with the assertion of legal defenses in accordance with the
proviso to the next preceding sentence (it being understood, however, that the
indemnifying party shall not be liable for the expenses of more than one
separate counsel, approved by you in the case of Article XX, representing the
Indemnified Parties under this Article XX, who are parties to such action), (ii)
the indemnifying party shall not have employed counsel satisfactory to the
Indemnified Party to represent the Indemnified Party within a reasonable time
after notice of commencement of the action or (iii) the indemnifying party has
authorized the employment of counsel for the Indemnified Party at the expense of
the indemnifying party; and except that, if clause (i) or (iii) is applicable,
such liability shall only be in respect of the counsel referred to in such
clause (i) or (iii).

                                RESPA Obligations

            Seller agrees to discharge on Purchaser's behalf all obligations,

have under the Real Estate Settlement Procedures Act of 1974, as amended, in
connection with Purchaser's purchases of Mortgage


                                       27
<PAGE>

Loans hereunder. Purchaser agrees to provide Seller with such information as is
reasonably necessary for Seller to discharge such obligations and hereby
appoints Seller as its agent in its name for the purposes of, and only for the
purposes of, performing such obligations. Seller hereby agrees to indemnify
Purchaser and its respective officers, directors, agents and employees from any
losses suffered by any such party in connection with Seller's obligations under
this Article XXI.

                                  ARTICLE XXII

                                    Survival

            All indemnities and undertakings of Seller and Purchaser hereunder
shall survive the termination of this Agreement.

                                 ARTICLE XXIII

                                Right of Set-off

            Upon the occurrence of any event or circumstance which requires
Seller to make a payment hereunder, Purchaser is hereby authorized then or at
any time or times thereafter, without notice to Seller (any such notice being
expressly waived by Seller), to set-off and apply any and all deposits (general
or special, time or demand, provisional or final), at any time held and other
indebtedness at any time owing by Purchaser to or for the credit or the account
of Seller against any and all of the obligations of Seller now or hereafter
existing hereunder, irrespective of whether or not Purchaser shall have made any
demand hereunder. Purchaser agrees promptly to notify Seller after any such
set-off and application made by Purchaser; provided that the failure to give
such notice shall not affect the validity of such set-off and application. The
rights of Purchaser under this Article XXIII are in addition to other rights and
remedies which Purchaser may have.

pursuant to Article XVIII hereof.

                                  ARTICLE XXV

               Submission to Jurisdiction; Waiver of Trial by Jury

            With respect to any claim arising out of this Agreement each party
irrevocably submits to the exclusive jurisdiction of the courts of the State of
New York and the United States District Court located in the Borough of
Manhattan, City of New York, and each party irrevocably waives any objection
which it may have at any time to the laying of venue of any suit, action or
proceeding arising out of or relating hereto brought in any such court,
irrevocably


                                       28
<PAGE>

waives any claim that any such suit, action or proceeding brought in any such
court has been brought in any inconvenient forum and further irrevocably waives
the right to object, with respect to such claim, suit, action or proceeding
brought in any such court, that such court does not have jurisdiction over such
party; provided that service of process is made as set forth in Article XXIV
hereof, or by any other lawful means. To the extent permitted by applicable law,
Purchaser and Seller each irrevocably waive all right of trial by jury in any
action, proceeding or counterclaim arising out of or in connection with this
Agreement or any matter arising hereunder.

                                  ARTICLE XXVI

      7. Subordination Provisions. The Purchaser covenants and agrees, and the
Seller, by its acceptance of this Note, likewise covenants and agrees, that the
payment of all Junior Liabilities is hereby expressly subordinated in right of
payment to the payment and performance of the Senior Liabilities to the extent
and in the manner set forth in the following clauses of this paragraph 7:

            (a) (i) In the event of any dissolution, winding up, liquidation,
readjustment, reorganization or other similar event relating to the Purchaser,
whether voluntary or involuntary, partial or complete, and whether in
bankruptcy, insolvency, receivership or other similar proceedings, or upon an
assignment for the benefit of creditors, or any other marshalling of the assets
and liabilities of the Purchaser or any sale of all or substantially all of the
assets of the Purchaser except pursuant to the Sale and Servicing Agreement
(such proceedings being herein collectively called "Bankruptcy Proceedings"),
and (ii) on and after the occurrence of an Event of Default, the Senior
Liabilities shall first be paid and performed in full and in cash before the
Seller shall be entitled to receive and to retain any payment or distribution in
respect of the Junior Liabilities. In order to implement the foregoing: (x) all
payments and distributions of any kind or character in respect of the Junior
Liabilities to which the Seller would be entitled except for this clause (a)
shall be made directly to the Indenture Trustee (for the benefit of the


                                      A-2
<PAGE>

Noteholders); and (y) the Seller hereby irrevocably agrees that the Indenture
Trustee (on behalf of the Noteholders), in the name of the Seller or otherwise,
may demand, sue for, collect, receive and receipt for any and all such payments
or distributions, and file, prove and vote or consent in any such Bankruptcy
Proceedings with respect to any and all claims of the Seller relating to the
Junior Liabilities, in each case until the Senior Liabilities shall have been
paid and performed in full and in cash.

            (b) following the occurrence of any of the events described in
clause (a)(i) or (ii), in the event that the Seller receives any payment or
other distribution of any kind or character from the Purchaser or from any other
source whatsoever, in respect of the Junior Liabilities, such payment or other
distribution shall be received in trust for the Indenture Trustee and shall be
turned over by the Seller to the Indenture Trustee (for the benefit of the
Noteholders) forthwith. All payments and distributions received by the Indenture
Trustee in respect of this Note, to the extent received in or converted into
cash, may be applied by the Indenture Trustee (for the benefit of the
Noteholders) first to the payment of any and all reasonable expenses (including
reasonable attorneys' fees and legal expenses) paid or incurred by the Indenture
Trustee or the Noteholders in enforcing these Subordination Provisions, or in
endeavoring to collect or realize upon the Junior Liabilities, and any balance
thereof shall, solely as between the Seller and the Noteholders, be applied by
the Indenture Trustee toward the payment of the Senior Liabilities in a manner
determined by the Indenture Trustee to be in accordance with the Indenture; but
as between the Purchaser and its creditors, no such payments or distributions of
any kind or character shall be deemed to be payments or distributions in respect
of the Senior Liabilities.

            (c) Upon the final payment in full and in cash of all Senior
Liabilities, the Seller shall be subrogated to the rights of the Indenture
Trustee to receive payments or distributions from the Purchaser that are
applicable to the Senior Liabilities until the Junior Liabilities are paid in

            (d) These Subordination Provisions are intended solely for the
purpose of defining the relative rights of the Seller, on the one hand, and the
Indenture Trustee (on behalf of Noteholders), on the other hand. Nothing
contained in these Subordination Provisions or elsewhere in this Note (subject
to paragraph 10 hereof) is intended to or shall impair, as between the
Purchaser, its creditors (other than the Noteholders) and the Seller, the
Purchaser's obligation, which is unconditional and absolute, to pay the Junior
Liabilities as and when the same shall become due and payable in accordance with
the terms hereof (subject to paragraph 10 hereof) and of the Purchase Agreement
or to affect the relative rights of the Seller and creditors of the Purchaser
(other than the Noteholders).

            (e) The Seller shall not, until the Senior Liabilities have been
finally paid and performed in full and in cash, (i) cancel, waive, forgive,
transfer or assign, or commence legal proceedings to enforce or collect, or
subordinate to any obligation of the Purchaser, howsoever created, arising or
evidenced, whether direct or indirect, absolute or contingent, or now or
thereafter existing, or due or to become due (other than the Senior
Liabilities), the Junior Liabilities or any rights in respect hereof or (ii)
convert the Junior Liabilities into an equity interest in the Purchaser, unless,
in the case of each of clauses (i) and (ii) above, the Seller shall have
received the prior written consent of the Indenture Trustee and the Insurer in
each case.

            (f) The Seller shall not, except without the advance written consent
of the Indenture Trustee and the Insurer commence, or join with any other Person
in commencing, any Bankruptcy Proceedings with respect to the Purchaser until at
least one year and one day have passed since the Termination Date.

            (g) If, at any time, any of the payment (in whole or in part) made
with respect to any Senior Liabilities is rescinded or must be restored or
returned by the Indenture Trustee or Noteholders (whether in connection with any
Bankruptcy Proceedings or otherwise), these Subordination Provisions shall
continue to be effective or shall be reinstated, as the case may be, as though
such payment had not been made.

            (h) The Indenture Trustee (on behalf of Noteholders) may, from time
to time, with the consent of the Insurer without notice to the Seller, and
without waiving any of its rights under these Subordination Provisions, take any
or all of the following actions: retain or obtain an interest in any property to
secure any of the Senior Liabilities; (ii) retain or obtain the primary or
secondary obligations of any other obligor or obligors with respect to any of
the Senior Liabilities; (iii) extend or renew for one or more periods (whether
or not longer than the original period), alter or exchange any of the Senior
Liabilities, or release or compromise any obligation of any nature with respect
to any of the Senior Liabilities; (iv) amend, supplement, amend and restate, or
otherwise modify the Sale and Servicing Agreement or any related document; and
(v) release its security interest in or surrender, release or permit any
substitution or exchange for all or any part of any rights or property securing
any of the Senior Liabilities, or extend or renew for one or more periods
(whether or not longer than the original period) or release, compromise, alter
or exchange any obligations of any nature of any obligor with respect to any
such rights or property.

            (i) The Seller hereby waives: (i) notice of acceptance of these
Subordination Provisions by any of the Noteholders, (ii) notice of the
existence, creation, non-payment or non-performance of all or any of the Senior
Liabilities; and (iii) all diligence in enforcement, collection or protection
of, or realization upon, the Senior Liabilities, or any thereof, or any security
therefor.

            (j) These Subordination Provisions constitute a continuing offer
from the Purchaser to all Persons who become the holders of, or who continue to
hold, Senior Liabilities; and these Subordination Provisions are made for the
benefit of the Noteholders and the Insurer, and the Indenture Trustee may
proceed to enforce such provisions on behalf of each of such Persons.

      8. General. No failure or delay on the part of the Seller in exercising
any power or right hereunder shall operate as a waiver thereof, nor shall any
single or partial exercise of any such power or right preclude any other or
further exercise thereof or the exercise of any other power or right. No
amendment, modification or waiver of, or consent with respect to, any provision
of this Note shall in any event be effective unless (a) the same shall be in
writing and signed and delivered by the Purchaser and the Seller, and (b) all
consents required for such actions under the Purchase Agreement and the Sale and
Servicing Agreement shall have been received by the appropriate Persons. The
rights and remedies granted hereunder to the Indenture Trustee and the
Noteholders are subject to exercise as provided in the Purchase Agreement and
the Sale and Servicing Agreement.

      9. Limitation on Interest. Notwithstanding anything in this Note to the
contrary, the Purchaser shall never be required to pay unearned interest on any
amount outstanding hereunder, and shall never be required to pay interest on the
principal amount outstanding hereunder at a rate in excess of the maximum
interest rate that may be contracted for, charged or received without violation
of applicable federal or state law.

      10. Acknowledgment. The Seller acknowledges and agrees that it has no
rights to payment under this Note, and will not make any claim for payment
hereunder, unless funds are available for payment by the Purchaser in excess of
amounts due and payable by it at the time under the Sale and Servicing Agreement
and under all similar notes issued by the Purchaser to the Seller in connection
with any previous or future securitizations.

      11. No Negotiation. This Note is not negotiable.

      12. Governing Law. THIS NOTE SHALL BE DEEMED TO BE A CONTRACT MADE UNDER
